Hi greatchap,

I have to ask if the prompt has been transcribed correctly. The answer choices all include the variable "A", which does NOT appear in the prompt. Given the inclusion of that variable, I have to assume that the original prompts stated that "A apples cost C cents..."; given that interpretation, here's how you could answer the question...

We're told that A apples costs C CENTS. We're asked how many apples can be bought for D DOLLARS.

IF...
A = 2
C = 2
D = 3
then 2 apples cost 2 cents, you can buy 100 apples for 1 dollar and 300 apples for 3 dollars. So we're looking for an answer that equals 300 when we plug in those 3 values... There's only one answer that matches.

GMAT assassins aren't born, they're made,
Rich

(A) 100acd (B) $$\frac{100d}{ac}$$ (C) $$\frac{ad}{100c}$$ (D) $$\frac{c}{100ad}$$ (E) $$\frac{100ad}{c}$$ We can also solve the question using equivalent ratios. Use the ratio number of apples/cost in DOLLARS First, notice that c DOLLARS is 100 times more than c CENTS So, if we can buy a apples for c cents, then we can buy 100a apples for c DOLLARS Let x = the number of apples that we can by for d dollars We can now set up two equivalent ratios. 100a/c = x/d Cross-multiply to get: (100a)(d) = cx Divide both sides by c to get: 100ad/c = x Answer: RELATED VIDEOS _________________ Test confidently with gmatprepnow.com Board of Directors Status: Stepping into my 10 years long dream Joined: 18 Jul 2015 Posts: 3620 Re: If a apple costs c cents, how many apples can be bought for d dollars [#permalink] ### Show Tags 09 Sep 2016, 05:31 It seems a wrong question. We cannot assume on our own that a is for the number of apples.

You could easily use this one Tactic on over half of the questions in that section, so it's an approach that you should plan to learn and practice often during your studies.

Hello Everyone,

Can anyone explain how to solve the following problem.

Question: If a apple costs c cents, how many apples can be bought for d dollars ?

(A) 100acd

(B) $$\frac{100d}{ac}$$

(C) $$\frac{ad}{100c}$$

(D) $$\frac{c}{100ad}$$

(E) $$\frac{100ad}{c}$$

Since each apple costs c/a cents, d dollars (or 100d cents) can buy (100d)/(c/a) = 100d x a/c = 100ad/c apples.
